Before my husband retired, he worked as a joiner for over 50years, and built and fitted many kitchens himself including some that were in Grade 1 listed buildings, where preservation rather than total replacement were very important. He always worked in solid timber, not a piece of plywood or MDF in sight, and most sinks where fashioned out of a single piece of stone, the Belfast sinks didn’t become popular until after Victorian times, and the most important kitchen assest was the large solid wood cooks table, the main work surface of the time. How things have changed, when we went shopping for our new kitchen, most suppliers didn’t even offer a solid timber framed kitchen, never mind one free from ply or MDF! Some where MDF and nothing else, built for show and not to last, so more profit for the kitchen suppliers of the future. We ended up going to a specialist trade supplier to buy our new kitchen, it’s solid timber framed, panels and doors. Only the shelving and backings are plywood, and it is paintable if ever we decided on a colour change in the future.
The problem with MDF is that it relays on a thin plastic foil wrap to repel moisture. Should that wrap become damaged in anyway, either by wear and tear or by the use of harsh cleaning chemicals, paint etc, then moisture can penetrate into the MDF and cause distortion and swelling, resulting in loss of strength. They are simply not built to last like the old kitchens where.
